ras,seinbled@relation` The cap" I 2 'includes in general'a horizontaltop Wall and a depending annular skirt portion. In the containerillustrated the cap is also of double Walled Aconstruction and includesinner. f and outer cup-shaped sheet metal shells and 2l, respectively.'Ihe top wallof the outer shell 2| is dished upwardly to give the top ofthecap a pleasing rounded contour. Upon reference to Fig. 2, it will beseen that the lower edges 22 of the outer rcap shell 2I arevfoldedinwardly over the adjacent edges of the inner cap shell 2|Jto form asmooth lower edge for the cap and at the same time, retain the shells inassembled relation with a firm clamping action.`

The cap I2 is detachably maintained in posiof intertting projections onthese parts. Thus,

in the preferred construction illustrated, generally helical ridges orthreads 23 are formed in the outer body shell II and cooperate withcomplementary inwardly extending ridges or threads 24 formed in theinner cap shell 20. It will thus be seen that even if the cap I2becomesstuck and the ruser exerts a strong torsional force in attempting tounscrew it, there will be no danger of twisting the inner and outershells with respect to each other as would be the case if the cap werethreaded on the inner shell, for example. At `the same time,l theadvantages of the smooth interior Wall construction which is so highlydesirable in a conta' er of this type are retained. i l

The lower end of the inner shell I0 is carried by a supporting disk 25loosely mounted Within the outer shell II. Thus, this disk rests on theinwardly and upwardly curled portion 26 of the outer shell II. A recessformed in the center of the supporting disk 25 serves to center the sameupon insertion of the inner shell I 0. The disk illustrated is providedwith an annular upstanding central portion 21, which is disheddownwardly as indicated at 28. In the assembly of the container, thedisk 25 is first dropped into the outer vshell II 'and rests loosely onthe projection 26. The inner shell I 0 is then inserted l into the outershell and as its lower end wall I3 is received by the recess 28, thedisk 25 is properly centered. During the completion `o1' the insertionof the inner shell IU, its edge portion I5 ispress fitted over the upperedge of the outer shell II. It will thus be seen that the assemblyoperation is 'very simple and that the component parts are also ofsimple construction with maximum tolerances in their dimensions.

Fig. 3 illustrates a modified form of frictional connection which may beutilized between the inner and outer shells oi a container of thegeneral type described above.

at the top of the outer shell Ila on which aV suitable cap suchpas thecap I2 described above may be telescoped. This neck portion termi-`nates in an upwardly facing shoulder I 8a which This container includesinner and outer shells I Da and I Ia which 'abuts the lower edge of thecap skirt. 'Ihreaded engagement 'between the cap and outer shell II ishad by complemental threads identical with those described above, one ofthe thread indentations 23'L on the outer shell IIa being indivvcated inFig. 3. In assembling a container having a joint such as-that shown inFig. 3, it is desirable to forrnthe seam 29.before the lower end `of thespace betweenv the vinner fand outer body shells is closed so that ananvil can be inserted therebetween for use in forming the joint. In suchcase, it is desirable to make the bottom supporting disk of exiblematerial or of such shape that it may be inserted after the insertion ofthe inner shell Illa.

Although certainpreferred embodiments of the invention have been shownand described in some detail for purposes of illustration, there is nointention to thereby limit the invention to such embodiments but, on theother hand, the appended claims are intended to cover all modivention.V

I claim as my invention:

'cations Within the spirit and scope of the -in- 1. A container of theclass set forth compris-V25 ing a tubular outer shell having aninwardly4x extending projection formed about at least a portion of thelower'end thereof, a supporting disk loosely mounted within said outershell on said projection, a cup-shaped inner shell inserted d into saidouter shell in the assembly of the container, said disk being providedwith a centrally located recess therein embracing the lower end of saidinner shell, whereby Asaid loosely mounted disk is centered by the lowerend of said inner shellupon the insertion thereof, and means securingthe upper portions of said shells together in assembled relation.

2. A container of the class set forth comprising a cup-shaped innershell and an outer shell disposed in spaced relation, the outer shellhaving its upper end Vportion offset inwardly to forman annular shoulderspaced below, the upper' end oi the outer shell and providing allintegral threaded neck portion'on the outer shell, said neck portion`being spaced outwardly from the upper end of the inner shell and saidinner shell having an outwardly flaring lip at its` upper endoverlapping the upper' end ofthe neck portion of the outer shell andlvclosingtheA upper fend of the space between the two shells, the'over.- 1

lapping portion of the lip .extending down yabout the neck insubstantiallyiiush relation withth'e threaded portion of thelatter andconstituting an extension thereof, and a cover, having a skirt l.

iitting over the neck portion of .the outer shell and having a screwthreaded connection with.. the outer shell through-the integral necklportiong` thereof.
